| The embeddedvision localization System based on the ARM integrates the techniques of computer numerical control, ARM, and digital image processing and analysis, etc. The research on the hardware and software of the embedded system ahd the arithmetic of digital image processing and analysis are the key of this thesis. The whole thesis is divided into seven chapters.In chapter 1, there is a introduction. At first, it summarized the development and trend ofvision localization technology and the present general situation of research all over the world. Then, the primary signification, content and purpose of this thesis are proposed.In chapter 2, there is a summarization of embedded system. The general situation of embedded system and ARM microprocessor is introduced briefly.In chapter 3, there is a introduction about digital image processing and analysis arithmetic. It is the key chapter of the thesis. In this chapter, all kinds of arithmetic used in vision localization system are introduced in detail, and some of them are improved in order to adapt well to the embedded system.In chapter 4, there is the total structure design of the embedded system. In this chapter, the design framework of hardware and software is proposed.In chapter 5, there is the design of system' s hardware. It is the key chapter of the thesis. In this chapter, the design of print circuit in details is illustrated.In chapter 6, there is the design of system' s software. It is also the key chapter. In this chapter, the design and realization of software in details is introduced, include BootLoader program, image acquisition program, image filtering program, image edge detection, image segmentation program and image localization program.In chapter 7, there is the debugging about the system. The results of the debugging are obtained.Finally, the research contents of this dissertation have been summarized, and the prospect of the vision localization technology based on the ARM has been opened up. |
